Issue with namespace using train.sh

[gsarti]

Hi,

I'm trying to run the training script with Python 3.8.10 and torch==1.10.2+cu113, and I obtain the following error:

>> bash thualign/bin/train.sh -s mask_align -e agree_deen
running mask_align

Do you have a specific pinned version of torch to make the script work?

I used Python 3.7 and pytorch 1.8.0

I used torch 1.7. I think it might be incompatible with torch>=1.9 as they introduced the torch/utils/data/_typing.py file.
